Base Station Connection Failure Reporting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in responding to connection failures, which can decrease the reliability of wireless devices without adequately managing signaling overhead or spectral efficiency.
Innovation Solution
A system where a base station central unit receives and forwards connection failure information from a distributed unit, allowing the central unit to evaluate and send updated cell parameters back to the distributed unit to reduce future connection failures, thereby improving communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection failure reporting mechanisms are implemented to improve reliability, then wireless communication reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential connection failure information (failure type, cell ID, timestamp) from the complete failure report, separating critical data from detailed diagnostics. This selective extraction reduces signaling overhead while maintaining reliability improvement benefits.
Solution Approach 2:
The patent applies different reporting qualities to different scenarios: detailed reports for critical failures, simplified reports for minor issues. This local quality approach optimizes signaling overhead by matching report detail to actual failure severity.
2Reliability
If connection failure reporting mechanisms are implemented to improve reliability, then wireless communication reliability is improved, but spectral efficiency decreases
Solution Approach 1:
The patent extracts only essential connection failure information (failure type, cell ID, timestamp) from complete failure reports, reducing the amount of signaling data transmitted and preserving spectral efficiency while maintaining reliability improvement benefits.
Solution Approach 2:
The patent implements periodic reporting only when connection failures occur, rather than continuous reporting. This event-triggered periodic action reduces signaling overhead and preserves spectral efficiency while still improving reliability through timely failure notification.
3Reliability
If updated cell parameters are determined to reduce future connection failures, then connection failure rate is reduced, but device complexity increases
Solution Approach 1:
The patent implements self-service evaluation at the base station central unit, which automatically determines updated cell parameters based on received failure information without requiring external network intervention. This reduces overall system complexity by localizing the decision-making process.
Solution Approach 2:
The patent establishes a feedback loop where connection failure information flows from distributed unit to central unit, which then determines updated parameters and sends them back. This structured feedback mechanism reduces complexity by creating a clear, automated response pathway.

AI summary
Systems, apparatuses, and methods are described for wireless communications. A wireless device may send, to a base station central unit, one or more first messages comprising information associated with a connection failure. The base station central unit may send the information associated with the connection failure in one or more second messages to a base station distributed unit for determining updated cell parameters.
